Abstract

Antenatal imaging is crucial in the management of high-risk pregnancies. Accurate dating relies on acquisition of reliable and reproducible ultrasound images and measurements. Quality image acquisition is necessary for assessing fetal growth and performing Doppler measurements to help diagnose pregnancy complications, stratify risk, and guide management. Further research is needed to ascertain whether current methods for estimating fetal weight can be improved with 3-dimensional ultrasound or magnetic resonance imaging; optimize dating with late initiation of prenatal care; minimize under-diagnosis of fetal growth restriction; and identify the best strategies to make ultrasound more available in low-income and middle-income countries.

摘要

产前影像学检查在高危妊娠的管理中至关重要。准确的孕周依赖于可靠且可重复的超声图像和测量。高质量的图像采集对于评估胎儿生长和进行多普勒测量以帮助诊断妊娠并发症、分层风险和指导管理都是必要的。需要进一步研究来确定当前估计胎儿体重的方法是否可以通过三维超声或磁共振成像来改进；通过延迟开始产前检查来优化孕周；尽量减少胎儿生长受限的漏诊；并确定使超声在低收入和中等收入国家更普及的最佳策略。
